Did you "cook" the sauce? What I mean is did you heat it to a cooking temp b4 you tasted it? I've been making my own bbq sauce for about 35 years, and it was after about 30 years that I realized the mix tasted different when "cooked". So now I always cook the mix b4 I call it ready to sauce with. Granted most of my experience is for grilling purposes, but sauce is sauce, man!
